Nothing's changed then, I went for a weekend break with my wife to Wales in the 1990s. It was closed, and the locals weren't very friendly, though no-one actually told us to fuck off. I guess their stance has hardened on that point since then. https://twitter.com/NigelEv97138643/status/1260103735193284614

On our way to Criccieth we stopped at a pub in Porthmadog for a quick drink, Everyone in the pub was speaking in English, as soon as I spoke in English, and they saw my Thai wife obviously wasn't Welsh, they all synchronized into the Welsh language, until we drank up and left .
